The data information retrieved from said facility and/or said facility device may be stored in a storage medium related to the management system. The data information may be stored in an external storage medium related to the management system. The
DK 2023 70292 A1 8 management system may comprise more than one storage medium. The storage medium may be a cloud database solution or similar.
The data information retrieved may be processed, sorted, filtered and/or reduced before being transferred/transmitted to the processing unit and/or storage medium in order to only transfer relevant, selected and/or anonymized data to the cloud and/or data storage medium.
Selecting and/or minimizing the data transferred and/or stored is an advantage in that it may significantly reduces the bandwidth and/or data capacity needed to use the system.
Selecting and/or minimizing the data transferred and/or stored further has the advantage that the unit transmitting the data may be operated in a power saving mode allowing the use of battery powered devices, detectors and/or transmitters. 18
Furthermore, only transferring and/or storing selected and/or reduced data may help data security and especially security of potential personal data. For example, in the case of sound data it is possible to avoid the transmittal and/or logging of language and sound indicators for personal activities and only transmit selected information such as events related to selected classifiers indicating specific activity i.e. toilet flush, a fall, door opening, distress call or distress related sounds etc.
Such reduced data sets may for example comprise or contain: a code for event type, time stamp for event start and/or time stamp for event stop.
At least part of the data processing such as sound data processing is preferably carried out at the facility i.e. before being transmitted to the cloud/remote part of the system.
Preferably a Machine Learning (ML) algorithm at the device or detector and/or in rela- tion to the device or detector may advantageously be used to select, filter, process, rec- ognize and/reduce the detected signal before sending to the cloud/remote part of the system.
Sound classifiers may in various embodiments be used to identify and categorize sounds detected. The ML sound classifier may preferably be pre-trained. In some setups, the
DK 2023 70292 A1 9
ML sound classifier is trained using raw sound data from the detection means. The raw sound data may for a selected time be transmitted to the management system for training the ML algorithm. The ML algorithm on the detection means or other device at the facility may be updated at regular pre-set intervals or when needed. In case raw sound data is streamed from the facility/device for example for the purpose of training the ML algorithm, the user, personnel etc. on site will be made explicitly aware of the sound recording.
The sound classified data may be transferred to the data management system constantly or when an event 1s detected by the sound classifier. It also an option to transfer the sound classifier data at specific times, in batches, by manual order etc. in case data is needed and/or gathered for statistical purpose.
Sound classifiers may be used to detect a number of different events e.g. start and stop of tap water, toilet flush etc. However, in advanced setups sound classifiers may even be used to detect the temperature of water as the temperature induced change in viscos- ity of the water may lead to variations in sound patterns.
Sound classifiers may also be used to detect specific water patterns, splashes etc. as the turbulence etc. results in different sounds and sound patterns from the water.
Sound classifiers may further be used for identification of:
Toilet flush, toilet malfunction, leaking toilet, valve failure in toilet
Tap/shower on/off, tap/shower running, amount of water flow from tap/shower, tap/shower malfunction
Use of toilet paper, extend of use of toilet paper
Use of air hand driers, use of electrical paper dispensers
Use of douche toilet, use of specified douche toilet function with pre-set ID
Use of soap or other dispenser functions with pre-set individual ID
Use of mechanical malfunction, degree of wear of mechanical devices, need for mainte- nance such as lubrication, shift of movable parts, tightening of joints, screws etc.
DK 2023 70292 A1 10
The method and system may also be arranged to recognize nationality/language of a user based on sound detection. The information provided via indication means may be localized or adapted e.g. based on the detected language.
The temperature of the room, water from one or more devices such as taps or showers, the user body temperature may also be detected via traditional temperature measure- ments and devices therefor and/or IR measurements. Based on the temperature infor- mation from the detection means, the method and system may indicate a need for show- ering in order to raise body temperature or otherwise lower or raise body, room, water, device temperature.
In a still further advantageous method of the invention, the method comprises further acts of - storing said data information from said facility in a storage medium related to the management system, such that a facility manager is capable of accessing the data infor- mation in the storage medium from a facility management user interface.
The data information retrieved from said facility may be stored in a storage medium related to the management system. One or more facility managers or other personnel and/or user types may be capable of accessing the data information in the storage me- dium from a facility management user interface or other approved interfaces. The maintenance crew may use a maintenance interface. The maintenance interface may have restricted access to the information in the storage medium related to the manage- ment system. The interfaces may be mobile units.
In various setups the method and system is implemented at an end user/owner different from the service provider. In this case it may be advantageous if the system is setup to ensure that data, preferably anonymized data, is collected by the system and that the system is configured to warn the end user/owner about critical events or the upcoming need for maintenance. Similarly, the method and system may detect device/detector malfunctions and transmit this information to one or more users via one or more indi- cating means and/or interfaces.
DK 2023 70292 A1 11
The invention is also directed at a management method for handling data information in a management system related to at least one facility, wherein the management system comprises a processing unit, a storage medium, at least one detection means and at least one indicating means, wherein the method comprises following acts: - retrieving data information from said facility using a data receiving unit, wherein the data information is provided by said detection means, - analysing the data information using said processing unit, - generating status information related to said facility and/or a facility device - transmitting an instruction based on the status information to at least one user type, optionally via the indicating means in the facility 2, such that a user is capable of re- ceiving information related to the status of said facility 2 and/or said facility device.
The features discussed in relation to the method herein also relates to the management system itself and vice versa. 18
The management system is configured to handle data information related to public, pri- vate or commercial facilities such as lavatories, kitchens etc. The management system comprises at least one detection means for detecting the use of one or more facilities having at least one facility device.
The management system comprises a processor unit which is configured to analyse at least one data information. The processor unit may also be configured to generate at least one status information based on the analysed data information.

The management system comprises at least one indicating means for indicating the sta- tus of said facility and/or said facility device, wherein the indication means is config- ured to send status information to a user of the facility and/or said facility device. The management system may also comprise at least one indicating means for indicating the
DK 2023 70292 A1 12 status of said facility and/or said facility device, wherein the indication means is con- figured to send status information to at least one facility management user interface and or to one or more other user types via text message, voice message, an app, push mes- sage etc.
The indicating means may provide information to a number of different user types. The user types may include a primary user {actual user of facility), caretaker (e.g. nurse or assistant helping the primary user), facility manager, service crew, guard, cleaning per- sonnel. The indicating means may be one or more of a lamp, speaker, text message, voice message, app and/or haptic feedback.
In an advantageous embodiment of the invention, the management system comprises a storage medium for storing data information and/or status information.
The management system may provide statistical information which relates to the use of the facility based on the data information and/or the status information.
The management system may provide statistics related to the user behaviour. The man- agement system may provide statistics related to the success of a positive reinforcement related to user behaviour. The management system may provide statistics related to health tracking during toilet use analysis. This can be used to detect diseases and/or disorders in an early stage. The management system may provide statistics related to resource consumption related to the facility.
In a further advantageous embodiment of the invention, the management system is con- figured to be accessible from at least one facility management user interface.
The management system may be configured to be accessible from at least one user in- terface. The user interface may be a facility management user interface used by a facility manager. The user interface may be an administrator user interface used by an admin- istrator, for example to perform an initialising set up of the management system and/or changing settings in the management system. The management system may also be ac-
DK 2023 70292 A1 13 cessed from a cleaning crew user interface and/or a service crew user interface. Differ- ent users of the management system may have different access clearance to the systems’ functions.
A user interface may be on a workstation, pc or laptop and/or via an app on a mobile device such as a telephone, watch or tablet.
In a still further advantageous embodiment of the invention, said indicating means com- prises a visual and/or auditory indicator unit.
This invention may provide a guidance to the user during use of the facility device or devices in the facility. The management system provides a solution for damage control, preventing lavatory facilities against overload, vandalism and improper use of the facil- ity device or devices in the facility with the use of indicating means and/or nudging 13 means. The indicating means and/or nudging means may e.g. be visual and/or auditory units.
In a further advantageous embodiment of the invention, said detection means comprise at least one detector unit configured to detect the status of said facility and/or said fa- cility device.
For example, the detection means automatically detect improper use or overload of the devices in the facility. The indicating unit automatically alerts the user of improper use or overload. The user must stop the ongoing action immediately. The indicating unit also automatically alerts the facility manager or other relevant user type that improper use or overload has occurred. The facility manager may send instructions to the service crew to check for example if something is broken. Every device may comprise an auto- matic built-in self-test, such that the facility manager gets information directly from the device itself and information if the device is broken. Alternatively, the facility manager may be capable to run a diagnostic program to test each one of the devices directly.
The present managements systems and the devices used for the methods may comprise primary and/or secondary units. Primary units may communicate with the cloud/remote
DK 2023 70292 A1 14 parts of the management system, other primary units and/or secondary units. The sec- ondary units may communicate with primary units and/or other secondary units. The system may comprise only primary units if desired.
The detection means and/or indicating means of the management system and method may be primary and/or secondary units.
Preferably, cloud connection is provided by a standard modem or telecom structures including e.g.3G, LTE-M1, 4G, Nb-IoT and/or 5G. Alternatively or in combination herewith local wifi, ethernet and/or LPW A-technology such as LoRaWan is used for cloud communication.
Primary and/or secondary units may communicate via BLE (Bloototh Low Energy) connection, Zigbee, Z-Wave, Lora and/or Wi-Fi. 18
Preferably, primary and/or secondary units are arranged to have a power safe mode as well as low energy data communication modes. The primary and/or secondary units may be at least partly battery driven, which is particularly advantageous in case of units with a power safe mode as well as low energy data communication modes.
In various setups the system is implemented at an end user/owner different from the service provider. In this case it may be advantageous if the system is setup to ensure that data, preferably anonymized data, is collected by the system and that the system is configured to warn the end user/owner about critical events or the upcoming need for maintenance.
The managements system and method may also be inter linked with visual or audio devices such as light dampers, speakers, light/image projectors.
For example, the light may be automatically dampened or changed to a warmer colour by activation of a lift. A light or image projector may also be activated by registration of a care situation such as changing or personal care of a user.
DK 2023 70292 A1 15
The system and method may also comprise means for voice control of one or more devices such as changing of water temperature, turn on light etc. Said voice control may in some embodiments be using the system’s sound classifier system.
In some embodiments the system may be integrated with existing home automation or home sound and/or home video system.
The system may also be arranged to provide temperature data from one or more types of temperature detectors. The temperature detectors may e.g. be IR temperature detec- tors or contact detectors in e,g. a toilet seat or in a support mat on a lift or care rest.
The system and method may be arranged to provide detailed information about a user's health status, weight etc., including detailed information about composition, amount, color, structure, odeur, frequency of feces and/or urine.
In case of detection of information relating to feces and/or urine, it may be an advantage that system and method is arranged to prevent or delay or otherwise control flush of the toilet for detection to occur in the toilet. The activation of detection means for health- related measurements, such as detectors in the toilet, may be induced by events detected by other detection means/devices e.g. based on statistics and/or learnings from the sys- tem.
Sound classifiers may be used to detect urine flow and/or amount. Similarly, sound classifiers may be used alone or in combination with other detectors to detect start of toilet use, type of toilet use and/or end of toilet use. Based on this type of data, the system and method may be able to evaluate the basic health status and even predict potential health issues such as constipation or urinary tract infections.
Detailed information regarding the weight of a user may e.g. be achieved form the toilet seat, toilet chair or similar during use. Especially measurements of weight over time may be used to get information flow, type, condition of feces and/or urine.
By the present method and system, it is thus possible to collect and/or analyse different types of health information from one or more users at single events and/or over a longer period thereby providing important information which for example may be used for health care protocols or indicating the need for medical care. The system and method
DK 2023 70292 A1 16 may be arranged to indicate health related issues and information to one or more user types.
User ID may be detected via a QR code, voice recognition, face recognition or similar.
All data relating to personal information may be anonymized or otherwise protected before transmittal and/or storage.
Installation of the system and or subsequent update or exchange of devices may be car- ried out on site or remotely. A user may enter a specified device ID into the system preferably together with location, type and/or use. The system may provide feedback for example in case the ID is already used or if the ID doesn’t relate to an existing device whereby typos and other errors may be avoided. The installation/registration of device
ID may be carried out/registered offline.
Subsequent registration of devices in the same location will allow the devices "to know" that they are in the same location and that they may communicate.
The device ID is preferably registered on the package of the device and/or in delivery papers. Preferably, the device 1s unique.
In case of error in a device it may be an advantage if the device ID is indicated on the device itself enabling to debug and e.g. locate a device which has been registered in a wrong location.
The system and method may thus for example be used for monitoring a lavatory facility with multiple users in a public space. In this case detectors such as microphones in or connected to a primary or secondary device with a sound classifier may be used to reg- ister one or more of - When someone enters - Use of toilet - Use of paper - Use of tap - Use of soap - Use of means for drying hands
DK 2023 70292 A1 17 - Use of changing facilities - Exits.
These data may be transmitted at each detected event or may be transmitted in prede- termined intervals or by request of a user such as a facility manager. The data in this case is not personalized and mainly of statistical use or for use in predicting need for cleaning and/or maintenance. Based on the detected activity, information may be pro- vided via indication means at the facility and/or to one or more other types of users in the same or other facility/location.
The system and method may also as an example be used in facilities in relation to per- sons needing extra nudging, care or monitoring such as people suffering from dementia or even children. In this case detectors such as microphones in or connected to a primary or secondary device with a sound classifier may be used to register one or more of - When someone enters - Use of toilet - Use of paper - Use of tap - Use of soap - Use of means for drying hands.
If the facility is a kitchen - use of stove ~ unintended use of and accidents in relation to cooking - opening/closing fridge - spillage
In general - Distress calls - Indications of confusion - Hyper activity - Lack of activity - Unexpected activity
These data may be transmitted at each detected event or may be transmitted in prede- termined intervals or by request of a user such as a facility manager. The data in this case the data may be directly linked to a person ID and thus protected from unintended
DK 2023 70292 A1 18 use. Based on the data information, the system may assist to e.g. ensure turning off water or the stove. The data information may also be used to inform of time of day, need for sleep, need for food etc. including guides on how to get/do it. The information pro- vided by the system may be standard instructions triggered by specific actions/events or may be personalized information, instructions and/or help based on statistics calcu- lated by the system based on data from the specific user and/or specific facility and/or facility device and/or based on information/instructions entered into the system by one or more users locally and/or remotely. Based on the detected activity, information may be provided via indication means at the facility and/or to one or more other types of user in the same or other facility/location for help, information, planning etc.
In case of users needing nudging, the method and system may provide various modes of nudging and/or gamifying.
An example is a "feedback plant”. The feedback plant may be arranged to signal based on one or more user activities. For example, the feedback plant may be arranged to change color based on a user's statistic in relation to washing hands after toilet use, brushing teeth, eating lunch etc. If the user is doing good, the plant will be green. If the user is doing less than good, the plant may be yellow. If the user is doing poorly, the plant may be red. The feedback device may also be shaped as a pet etc. The feedback plant may be arranged near the feature it is intended to give feedback on e.g. in the bath room. However, if it is arranged in another room or location, it may be a remote re- minder and trigger of an action for the user. In relation to the present method and sys- tem, the feedback plant may be used as the indicating means.
Another example of effective nudging/gamification may be the "target fly” in a toilet, providing an aim when urinating. The target may be arranged to detect if it is hit or not thereby giving feedback in form of a rating, sound or change of color etc. The target may be static, or it may be movable by automation e.g. by interaction with the method and system in which case it may be considered an indication means and/or a detection unit.
DK 2023 70292 A1 19
The information detected, stored and/or transmitted by the system and method may be used to assist single specified users, groups of users, unknown users etc. The infor- mation detected, stored and/or transmitted by the system and method may be used to predict times of increased activity, needs of various primary users, best mode interac- tion/indication via indication means, notice changes in behavioral of individuals and/or average user types of users and preferably indicating and/or transmitting information related hereto. Patters for detection such as predetermined activation of detection means and/or devices may be based om learnings and/or statistics from the information de- tected, stored and/or transmitted by the system and method.
The invention has now been explained with reference to a few embodiments which have only been discussed in order to illustrate the many possibilities and varying design pos- sibilities achievable with the management system and the method related to a manage- ment system according to the present invention. 18

PIR sensor
A PIR sensor may be implemented for touch free application. The PIR sensor may then be used also for retrieving data or active other devices.
Temperature sensor
An analogue temperature sensor may be used for mounting on pipes for monitoring a water flow.
The water supply flow to a toilet cistern, as well as a faucet's cold and hot water supply may be relevant to measure as this can indicate an activation action, the duration of the activation action, as well as a leak that causes a sustained activation.
Thorough research has illustrated that this can be realized in a highly cost-effective way through simple technology used in the correct way, as described below.
Studies have shown that the measurement method must be able to reliably measure tem- perature changes of at least around 1/1000 degrees Celsius with an iteration time of one second. Through appropriate signal analysis, this allows one to reliably detect when a water flow starts and stops.
The method has the following properties: + The sensor can be easily retrofitted onto standard fittings via a mounting adapter and without interfering with the water installation by disassembling and reassembling water pipes. This means that a plumber is not required for proper installation, which reduces installation costs, the risk of subsequent water leakage, but also the installation time. » The sensor does not require maintenance.
DK 2023 70292 A1 23
A very cost-effective design uses a so-called NTC thermistor. It is an electrical compo- nent who's resistance value changes significantly as the temperature changes, relative to alternative sensor types. The resistor material is typically encapsulated in an epoxy and pre-terminated with wires, which is the preferred sensor element wrapping variant for the described use.
The sensor is typically connected to the signal processing device via a set of wires, meaning it can be several meters away. This also has the cost advantage that the signal processing untt does not necessarily need to be protected against condensation as it is typically not cooled below condensation temperature as the sensor element often 1s, e.g. when measuring on a cold-water pipe.
The outer sensor wrapping may comprise a mounting adapter, which ensures that the sensor can be easily attached to the side of the pipe on which flow is to be measured.
Between the pipe and the sensor, a thin heat-conducting polymer or paste may typically be fitted to ensure good thermal contact between the two.
The mounting adapter is typically constructed from a poor heat conductor e.g. plastic.
If the mounting adapter is constructed from a good heat conductor, the contact surface between the sensor element and the mounting adapter must preferably be thermally in- sulated. This grants the sensor element a temperature that is primarily influenced by the temperature of the metal pipe.
A correct mounting location is a prerequisite for the sensor to reliably distinguish be- tween a water flow that is either initiated or stopped with a response time less than five seconds. The mounting location must be a place with direct metal contact between the sensor and the water to be measured, possibly via a thread. This could be on the outside of a metal adaptor for an extension hose, at a pipe joint or directly on a metal pipe.
Weight sensor for detection of general use versus vandalism:
General use:
DK 2023 70292 A1 24
An activation action value (trigger criterion) may be determined during the production of the system. When the measured weight exceeds the activation action value, the acti- vation action is triggered and when the measured weight value falls below the activation action value, the activation action comes to an end.
If the sensor measurement tends to slowly alter its offset, the following method can be used. This method is based on the assumption that a sensor is usually not exposed to activity. The measurement over for example the last 24 hours when there is no activity, is used to establish an ongoing reference for ceased activity.
The activation criterion for activity is therefore a sudden change from a reference meas- urement. And when the sensor returns to the ongoing reference, it triggers the ceased activity criterion.
Alternatively, the trigger criterion can be chosen as continuous variations in weight above a given value over a given time. The trigger criterion for cessation of activity is selected as continuous vartations in weight below the given value over a given time.
This means that weight gradients over a given measurement time are used as a trigger criterion.
Alternatively, the trigger criterion can be selected as combinations of the above.
Overload:
Detecting non-compliance in terms of overloading requires a suitable sensor technology that, in addition to normal use, also can measure the degree of loading, making it pos- sible to detect an overload.
The device subject for measuring overload may include a height-adjustable toilet and/or a height-adjustable changing table.
Overload refers to excessive static or dynamic impact on a surface adapted for a person to sit or lie when used.
DK 2023 70292 A1 25
To minimize or eliminate maintenance costs and provide good protection against van- dalism, a sensor based on force measurement in conjunction with the actuator that reg- ulates the height of the toilet or changing table may be very desirable.
Alternative measurement methods may be used:
The load can be measured as a force and can happen inside the actuator itself, in con- nection with the bottom mounting of the actuator, or a fixed anchor point connected to a chainring bottom bracket.
Force measurement can also be performed on moving points but may unnecessarily complicate the concept.
The sensor type may typically be referred to as a load cell.
A load may also be determined through torque measurements by use of deflection sen- sors fx. strain gauge or inclinometers. 18
Data acquired at the facility in the management system can be used for two purposes:
Help and maintenance.
Example of voluntary help:
A situation where a non-compliant application is used to alert the system user in order to voluntarily stop the bad application.
Non-compliant use can be either too prolonged use or a load that exceeds the specified load for a shorter or longer period of time.
For example, an on-site user receives an immediate acoustic reminder in the form of an annoying or deterrent sound as soon as a non-compliant use occurs in connection with a changing table, e.g. a pulsating beep sound or an alarm clock-like sound depending on the type of unwanted use.
Another example of voluntary help is nudging. See the logic description under "Exam- ples of local data processing”.
Nudging methods:
DK 2023 70292 A1 26
Light or movement nudging:
H.g. when an on-site user needs to be nudged to wash their hands or use soap, this is typically done through a pleasant notification in the form of constant or flashing lights, or a moving object close to water faucets or soap dispensers.
When the nudging stops, the light turns off.
Voice guided nudging:
This can either be proactive and only say something before the user performs the action.
This option will probably be the most popular as the user will only feel monitored to a limited extent.
Ex. The system says "Remember to wash your hands” or "Remember to use soap when washing your hands” or "Remember to use soap when washing your hands for at least seconds” 15 Proof of evidence of effect is best achieved via sensors to detect water flow or soap application. These do not affect the user's sense of being monitored.
Nudging can also be reactive to varying degrees.
It can start by saying remember to wash your hands.
If the water then runs for too short a time, the system reacts and prompts you to wash for another 15 seconds, for example.
If no soap is used during hand washing, the system reacts and prompts you to use soap and wash for e.g. 15 seconds.
If an acknowledgement function is desired, the user can acknowledge with a word such as yes or ok, which is interpreted by a sound classifier that is activated by the words yes and ok. A voice-based receipting should be carefully evaluated in view of the users feeling of privacy.
Alternatively, acknowledgement can be achieved via sensors to detect water flow or soap application.
Example of involuntary help:
A situation where a non-compliant application is used to summon a predetermined guard and/or a predetermined maintenance manager depending on the nature of the ap- plication.
DK 2023 70292 A1 27
A supervisor can receive a text message with an incident description and the address of the system location as soon as a non-compliant use occurs.
Non-compliant use can be either too prolonged use (Sleeping alarm) or a load that ex- ceeds the specified load for a shorter (impact) or longer period of time (overload).
In other words, the system sends information to different user types depending on their relevance and in a manageable format.
Example of maintenance:
A cleaning manager receives a text message or email informing that a system with a given address has been used as soon as an application is completed.
Both a cleaning manager and a system owner can access a cloud portal to get an over- view of when a given system or many systems have been used in a given period, e.g. via a spreadsheet or Power Bi interface. The same information can also be sent to pre- selected users at a pre-selected fixed interval via email, for example, once a month.
In the event of a non-compliant use involving a load that exceeds the specified load for a shorter or longer period of time, the maintenance manager can receive a text message or email with an incident description, advice on how to check the product for normal function, contact information for the service organization behind the system, and the address of the system location every time an overload occurs.
In all of the above examples, a smartphone app can of course also be used. However, it is relatively costly to develop and operate. In addition, the user must likewise own a smartphone, which also increases the total operating costs for the user.
Data processing and transmission:
What data can be selected
The selected data can reliably and cost-effectively represent the type of activity to be measured. Here, cost-effective represents a total consideration of development costs to realize the interpretation of the data type, installation costs, and ongoing costs to main- tain the data source.
From this, it is decided to select data from a single weight sensor designed as a load cell placed in a carefully selected location in a changing table or toilet to represent usage info and short or long-term overloads.
DK 2023 70292 A1 28
Based on this, it is decided to select data from a water flow sensor based on temperature measurement to represent usage info and usage time for water flow for both a toilet and sink (faucet, washbasin).
From this, it is decided to select data from a PIR sensor with a narrow detection angle to detect activity close to a soap dispenser (and or sink).
The use of data from sound sources is in many ways very attractive from an installation and maintenance perspective but is developmentally challenging in terms of cost due to the complexity of ensuring high reliability of the sound classifier when the microphone harvesting the data is disturbed by extraneous sound sources.
Data from sound sources only really makes economic sense when the sound source originates from a human, where alternative sensor technologies are less attractive.
In terms of development, it is also an economic advantage to only be able to identify simple human sounds such as yes and no, and a two-way communication between sys- tem and human where the human only has to say simple sounds is therefore preferable.
Privacy concerns also motivates to limit the number of identified sounds.
A more complex sound classifier that can identify the sound of a person falling and distress sounds (e.g. calls for help) can also be combined with human feedback acknowledgement in the form of "yes or no” to reduce the number of false identifica- tons.
What can be processed on-site (local processor)
There are four criteria for local data processing 20- Response time — The information being processed can optionally result in an immediate response. This includes overload cases and hygiene-related nudging in connection with hand washing. The use of an external processor will require a response time of max one second, which cannot always be guaranteed with an information transport path that uses a cellular network.
This means that high system reliability is compromised. 2- Cost- Desire to minimize data exchange with external processes from a cost perspective. For example, when using an information transport path that uses a cellular network, this consideration 13 particularly attractive as increased data volume is subse- quently charged for.
DK 2023 70292 A1 29 3- Connectivity — It makes good business sense to not add extra installation cost to ensure a high success rate for cloud connectivity. Adding an external antenna to com- pensate for a bad antenna signal may for that reason not be considered attractive. A common feature of wireless network technologies such as cellular networks is that there is a correlation between high data transmission capacity and the requirement for a strong antenna signal. This means that a location in a basement and/or far away from an an- tenna mast will result in a weak antenna signal and therefore a low data transmission capacity. A modern 5G technology like NB-IoT offers low transmission capacity and can tolerate a weak antenna signal and increasingly has global coverage. Low trans- mission capacity goes hand in hand with a high degree of local data processing. 4- Ease of use — The criterion that was the main reason for choosing the other three criteria. There is often an option for a virtually free high-capacity data connection to an external server via a wireless LAN network in the area where the system is to be installed. However, the area 's IT manager typically does not want foreign IT equipment connected to the area's LAN or wireless LAN network for IT security reasons. The system is considered foreign IT equipment and it is thus a contractually a heavy docu- mentation task for each installation site to have the system recognized as IT secure equipment.
If the cellular infrastructure is used as a data connection to an external server instead, there is no interaction with the site’s LAN or wireless LAN network and no documen- tation task regarding IT security. This means that the ease of installation will be very good.
On the other hand, the cellular infrastructure presents an ongoing challenge in terms of the cost of the data connection. This generally becomes smaller as less data 18 ex- changed, which increases the incentive for a high degree of local data processing and minimal data exchange with external servers.
Examples of local data processing:
Detection of water flow through water temperature analysis 30 . The measurement method is simple to realize, meaning that a simple signal analysis based on gradient estimation can provide high detection reliability and calcu- late when a flow starts and when it stops again. This means that the measured tempera- ture changes slowly over time when the water is still and the measured temperature changes quickly over time when the water is moving.
DK 2023 70292 A1 30 . If a water leak occurs, the measured water temperature is atypically high or low over a longer period of time. . All threshold values are local. For example, the temperature gradients thresh- olds for starting and stopping water flow and the flush time threshold for a large or small flush. A min. water flow timer related to nudging as well as atypical high or low water temperature threshold and detection time threshold before leak calls. . All threshold values can be continuously evaluated in the cloud with periodic data extraction of time series regarding the measured temperature. Following the eval- uation, all local thresholds are automatically updated. 10 . The evaluation can be done manually with time series analysis and statistical tools or automatically via machine learning algorithms.
What can be transmitted for external processes (server/cloud):
Data sent to external processes may all have been through local processing first and an extract of this can be sent to external processes if the criteria below are met.
Activity changing table
When the criteria for activity at a changing table is no longer met, a code indicating that the changing table has been activated and the duration of the activity is transmitted to the external processor. This information represents the highest degree of signal com- pression. {Activity can trigger a cleaning call).
In addition, optional meta data can be included in the form of a data set for average and peak measurements during the measured load period. Meta data can be used by the system owner to achieve an overview of the degree to which the equipment has been close to being overloaded.
In addition, optional meta data can be included in the form of a data set for repeated measuremenis with a fixed time interval of average and peak measurements throughout the measured load period. Setting the time interval to e.g. 2 to 5 seconds gives a very detailed picture of how the system is being used. Meta data can be used by the system owner to achieve an overview of the degree to which the equipment has been close to being overloaded.
In a start-up phase, it can make sense to choose metadata as it provides a good under- standing of how the system is used by the end user, but in the Jong term, this info does not provide significant added value and can therefore be deselected.
DK 2023 70292 A1 31
Overload or impact on changing table
When the overload or impact criteria are met, a code indicating that the changing table has been overloaded with the weight of said overload being transmitted to the external processor. This information represents the highest degree of signal compression. (Over- load can trigger a call to a guard and a maintenance manager).
In addition, optional meta data can be included in the form of a data set for repeated measurements with a fixed time interval of average and peak measurements throughout the measured load period until the load ceases. Setting the time interval to e.g. 2 seconds gives a very detailed picture of how the system has been used. Meta data can be used by the system owner to get an overview of what happened in the period around the overload, which can be especially relevant in connection with compensation for dam- aged inventory.
Sleeping alarm regarding changing table 13 When the criteria for activity at a changing table has been met for long enough, the sleeping alarm criteria is triggered. A sleeping alarm code is then transmitted to an ex- ternal processor. This information represents the highest degree of signal compression. (Sleeping alarm can trigger a call to a guard)
Use at a toilet
Weight measurement:
The same criteria apply here as with a changing table when it comes to weight load.
When used as part of a nudging feature, activity time is used as soon as the activity ends.
Water flow:
In the case of water flow detection, a distinction is made between normal use and a fail situation.
If the criteria for a small or large flush are met, a large or small flush code and water flow duration is transmitted to the external processor. This may trigger a cleaning call.
If the maximum flush time or small leakage criteria is exceeded, a large or small water leakage code and water flow duration is transmitted to the external processor. This may trigger a call to a maintenance manager.
DK 2023 70292 A1 32
Use at a hand washbasin
Water flow:
In the case of water flow detection, a distinction is made between normal use and a fail situation.
If the maximum flush time or small leakage criteria is met, a large or small water leak- age code and water flow duration is transmitted to the external processor. This may trigger a call to a maintenance manager.
Information on normal water flow can be relevant here in the form of usage time of either cold or hot water or both. When the flow criterion ends, a code for cold or hot water and the duration of the water flow is transmitted to the external processor or lo- cally in a nudging case.
Nudging
The system is designed to communicate wirelessly directly between multiple secondary devices with a short-range communication form such as BLE. If several secondary de- vices are used in a context where they need to communicate with each other in a nudging case, the inter-communication between secondary modules in that context should not be considered as communication to external processes.
However, in the absence of a BLE interface, the above-mentioned communication can happen via an external processor. Here, however, the external processes simply act as a data transport path that is rated.
All data on nudging scope and success rate is continuously sent to external processes if this type of overview is selected. A statistical overview can therefore be extracted from here.
When is data collected
Typically, a given signal from an analog sensor needs to be measured locally 5 to 100 times per second. This raw signal is sent to an algorithm that continuously calculates gradient, peak, and average values once per second. This signal now contains four val- ues, which is referred to as a pre-processed signal.
The pre-processed signal is then passed on to algorithms that measure whether it is greater or less than various limit values. If this happens, different timers are initiated or stopped. Passing these timers at different limit values can trigger an event detection trigger criterion.
DK 2023 70292 A1 33
The method and the facility system may advantageously be used in mobile facilities for reducing facility maintenance costs and increasing personal safety (distress call}.
Reduced maintenance costs
When maintenance becomes condition-based rather than callout-based, an opportunity to perform maintenance on a more informed basis is provided and maintenance will therefore often happen less frequently. This means time spent on cleaning and consum- able refills such as toilet roll and soap can be reduced during periods of limited use.
Increased personal safety
Scenario I:
When vandalism 1s detected as soon as it occurs, the time it takes to report the equipment failure is reduced. This reduces the risk of a normal user being injured after using faulty equipment that has not yet been reported.
Scenario 2:
If a user falls in the bathroom environment, the fall sound can be used to trigger a sound classifier for fall sounds.
If the user shouts for help, produces complaint sounds, or similar, this can trigger a sound classifier for distress call.
In both cases, the system can now audibly say: “Should assistance be called? Answer yes or no” The user's answer “yes or no” is detected by a sound classifier for yes and no sounds. The system now responds in one of four ways to reduce the number of erro- neous calls for assistance. 20- The system says "response not understood. Should assistance be called?
Answer yes or no” 2- The system says “response not understood. Assistance is called” 3- The system says “answer understood. Assistance is called” 4- The system says "answer understood. Assistance is not called”

It is to be understood that the invention is not limited in its scope to the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or carried out in Various Ways.
Fig. 1 illustrates an embodiment of a management system 1 for handling data infor- mation related to a facility 2. The management system I handles data information and status information to and from a facility 2 via data communication. The management system 1 may be part of the facility 2. The management system may be a part of an external solution, such as a cloud solution or similar. The management system may be accessed for user interfaces, such as an administrator 6 user interface or a facility man- ager 3 user interface 45. The administrator configures the management system 1, such that the one or more lavatory facilities are correctly registered in the management sys- 13 tern 1. Enitializing settings 7,8,9 which are registered in the management system 1 may be information such as identification number of the facility 2, the location of the facility 2, device information and detection limitation, warning and/or alert information, time schedule and maintenance information etc. Maintenance tasks are handled by the clean- ing crew 4 and the service crew 5. Maintenance tasks may be controlled by the facility management.
The management system | comprises detection means for detecting the status of the facility. The management system 1 comprises detection means for detecting the status of at least one facility device 10, 11, 12, 13. The management system I may be config- ured to retrieve data information from the facility 2 before, during and after the user uses the facility 2. The management system I comprises detection means for detecting the status of secondary functions in the facility 2, such as the condition of temperature in the room, the condition of the floor, the condition of the light etc. The management system 1 is capable of retrieving this information.
The management system 1 comprises indicating means for indicating the status of said facility 2 and/or said facility device wherein the indication means is configured to send status information to the user before, during and after the use of the facility.
DK 2023 70292 A1 37
The management system | comprises a processor unit 14 configured to analysing the data information and generating at least one status information based on the analysed data information. The management system 1 may provide statistical information which relates to the use of the facility 2.
The management system 1 also comprises data communication means configured to receive and send data information and/or status information between the management system and the facility and/or said facility device or said processer 14 close to the facil- ity device. The data communication means may comprise wireless data communication to and from the management system I and the facility 2.

Fig. 2 shows an embodiment of a facility 2. In this embodiment, the facility 2 comprises a facility device, such as a toilet 10, a washbasin 11, dispensers 12, and a changing table 13. Every one of the facility devices may be provided with one or more detectors. The detectors may be sensors specific for the purpose of the measurement. Alternatively, the facility 2 may be provided with at least one microphone or similar. By analysing the user's movement and the use of the devices, the user's behavioural pattern can be iden- tified and predicted. Using nudging to positively reinforce a certain behavicural pattern may be provided with the use of indicating means. The indication means may be a visual and/or an auditory indicator unit provided in the facility 2. A visual indicator unit may be light from one or more lamps. An auditory indicator unit may be sound waves from a speaker or a buzzer or similar. These units are shown in fig. 2b.
Fig. 3a, 3b and 3c illustrate the use of warning and alert features. The warning or alert is activated if devices are out of order or subject to improper use or overload etc. Infor- mation regarding devices being out of order or subject to improper use or overload etc. is sent to the facility manager, fig. I, 3. And/or guard 5. The facility manager sends instructions to the service crew 5. Furthermore, the user of the lavatory also receives
DK 2023 70292 A1 38 information, using visual or auditory information, for example sound through a loud- speaker or flashing light, telling the user something is wrong.
Fig. 3a illustrates overload of the changing table. The detection means automatically detect a weight load larger than maximum allowed load. An indicating unit automati- cally alert the user that the changing table has exceeded the weight limit. The user must stop the ongoing action and remove the weight on the changing table immediately. The indicating unit also automatically alerts the facility manager that the changing table has exceed the weight limit. The facility manager may send instructions to the service crew to check the function of changing table to see if the changing table is broken. The chang- ing table may comprise an automatic built-in self-test, such that the38ave3Bityy man- ager gets information directly from the changing table if the changing table is broken.
Alternatively, the facility manager may be capable of running a diagnostic program to test the changing table directly. 18
Fig. 3b illustrates improper use of the changing table. The detection means automati- cally detects fluctuating weight load (impact). An indicating unit automatically alerts the user to stop the ongoing action and remove the item causing the fluctuating weight load on the changing table immediately. The indicating unit also automatically alerts the facility manager that fluctuating weight load has been observed on the changing table.
Fig. 3c illustrates improper use of the changing table. The detection means automati- cally detect a constant weight load on the changing table for a period of time exceeding the allowed period of time. An indicating unit automatically alerts the user that the weight load on the changing table must be removed immediately. The sound may be similar to an alarm clock. This may prevent people from for example sleeping on a changing table. The indicating unit also automatically alert the facility manager and/or guard 5 that a constant weight load on the changing table for a period of time has been observed.
Figs. 4 and 5 illustrates two embodiments of a temperature sensor for mounting on pipes for monitoring a water flow 20 in a metal conduit 22. The temperature sensors comprise
DK 2023 70292 A1 39 a mounting adapter 26, a thermistor element 28 with cables 30, a thermally conductive polymer or paste 24 and a thermally isolating element 32.
Figs. 6-8 illustrate embodiments of weight or load measurements on a changing table 13. Fig. 9 illustrates one embodiment of weight or load measurements on a height ad- justable toilet 10.
The illustrated embodiments in figs. 6 and 9 use an actuator 40 for performing a height adjustment of the changing table and the toilet, respectively. The toilet is adjusted by displacing the toilet along a chassis whereas the changing table is displaced by use of a chain system 42.
The weight or load on the device can be determined by use of one or more load cells 44 placed in strategically points in the installation. 18
Fig. 7 illustrates another embodiment of a changing table 13 and corresponding load measurement method, where the vertical forces between all contact points to wall point and floor of the rack holding the table are measured. The sum of these force measure- ments 1s an expression of the total load force and the load from the user can be directly deduced hereof.
Fig. 8 illustrates yet another embodiment of a changing table 13 with a measuring method consists of one or two force gauges placed at the stop point of the changing table’s pivot, which ensures that the table remains horizontal. The changing table has two swivel joints. With increased bed load, the measured force F at a well-defined dis- tance from the swivel joint is a direct expression of the applied torque T, which can also be a relevant measurement parameter for overloading.
A variant of the measurement method consists of one or two torque meters T placed close to the rotary joint of the changing table. With increased table load, the measured torque is a direct expression of the applied torque. The torque meters can be suitably realized as load cells located close to the pivot point, which measure deflection in the chassis frame of the changing table.
DK 2023 70292 A1 40
Figs 10 a-c illustrate that when a torque is applied from a changing table top, it will cause a deflection in the horizontal chassis 52. The deflection at points 54, 56 will bend inwards or outwards depending on the height of the table and the magnitude of the torque T. Analysing points 54 and 56 together can therefore derive both the height of the table and the magnitude of the torque. The deflection in points 54 and 56 can be measured with strain gauge sensors 37 or inclinometers 36 that measure the angle to the direction of gravity.
An important feature of this measurement method is that a permanent deformation in the vertical chassis due to overloading can be measured immediately after the changing table is no longer in use. This is relevant info for a maintenance manager.
A variant of the torque measurement method consists of one or more deflection sensors placed on or in the horizontal chassis that holds the changing table. When a torque T) is applied from the changing table top it will cause a deflection in the vertical chassis.
This is best measured in point 60. The deflection in point 60 can be measured with a strain gauge sensor.
A variant of the torque measurement method measures the angle to the direction of gravity at point 58. This will also be influenced by the degree of bending in the hort- zontal chassis discussed above. Without taking into account variations in the deflection of the vertical chassis, this measurement method offers a relatively simple and inexpen- sive way to estimate the applied torque but with limited accuracy due to unknown table height. If information from e.g. an actuator contains table height, this can be included in a more accurate torque estimate.
An important feature of the inclinometer measurement method in point 58 is that a per- manent deformation in the horizontal or vertical chassis due to overloading can be meas- ured immediately after the use of the changing table has ceased. This is relevant info for a facility manager 3 or service crew 5.

Figure 11 illustrates the flow diagram for data resulting in a status of ‘acute clean- ing /activity.
When the measured weight has been bigger than a activity threshold limit for a certain threshold time, the criteria for activity is reached.
When the measured weight has been smaller than a threshold limit for a certain thresh- old time, the criteria for inactivity is reached.
In that case the information is sent to the cloud to be optionally forwarded to the clean- ing crew 4.
Figure 12 illustrates the flow diagram for data resulting in a status of ‘Overload’.
When the measured weight has been bigger than a threshold limit for a certain threshold time, the criteria for overload is reached.
In that case a nudging sound is generated locally to warn about a non-compliant use.
An info 1s sent to the cloud to be optionally forwarded to the facility manager 3 and/ or a guard 5.
The nudging sound continues until the measured weight is at an inactivity level.
Figure 13 illustrates the flow diagram for data resulting in a status of ‘Impact’
When the measured weight has been bigger than a threshold limit (typical the overload limit) and lower than a lower threshold limit a specific number of times within a specific time frame, then the criteria for impact 18 reached.
In that case a nudging sound is generated locally to warn about a non-compliant use.
DK 2023 70292 A1 42
Information is sent to the cloud to be optionally forwarded to the facility manager 3 and/ or a guard 5.
The nudging sound continues until the measured weight is at an inactivity level.
The criteria may be intended to detect if a user is jumping on the equipment 10 and 13 in a non-compliant way.
Figure 14 illustrates the flow diagram for data resulting in a status of ‘Sleeping alarm”.
When the measured weight has been bigger than the activity threshold limit for a certain threshold time, the criteria for sleeping is reached.
In that case a nudging sound is generated locally to warn about a non-compliant use.
Information is sent to the cloud to be optionally forwarded to the facility manager 3 and/ or a guard 5.
The nudging sound continues until the measured weight is at an inactivity level.
The measured weight has to be at an inactivity level for specific threshold time to avoid that the nudging sound reappears the same time the measured weight is bigger than the activity threshold limit.
Figure 15 illustrates an algorithm for monitoring the use of a toilet 10: . When the signal analysis detects a water flow to the cistern, a timestamp is stored locally. The signal is transmitted to an optional nudging feature related to hand washing. . When the signal analysis detects that the water flow stops again, a signal is sent to the cloud that the toilet has been used and the duration of the water flow. Infor- mation on the duration of the water flow indicates whether there has been a large or small flush -> urine or faeces, which is relevant information in relation to a cleaning call, as the degree of contamination is different in the two cases. » If the flush time exceeds the maximum flush time, there is a large leak and this information is then sent to the cloud to be relayed to a facility manager 3. . The flush time can be included in a cloud algorithm that estimates the need for toilet paper refills, as paper consumption is significantly different for the two types of use. . The interpretation of the length of a flush as a large or small flush is initially done locally based on a default threshold time. If it 183 exceeded, it 1s a major flush.
DK 2023 70292 A1 43 . This information is passed on to the optional nudging feature related to hand washing,
An alternative way to determine big or small flush in a nudging case is the following:
The optical movement sensor 38 in the system can be used as a touchless flush button.
The small flush I activated as soon the hand is close the sensor.
If the hand is in the flush position for eg. 2-3 seconds then it indicates that the user wants a big flush and the flush time just increase from a small to a big flush.
This information can be used by the processer unit 14 in the same way as the small/big flush estimate from the water flow sensor.
The processer also has the ability to generate an electrical signal that can initiate a toilet flush.
Figure 16 illustrates an algorithm for monitoring the use of a washbasin 11: . When the signal analysis detects a water flow, a timestamp is stored locally.
The signal is transmitted to an optional nudging feature related to hand washing. . When the signal analysis detects that the water flow stops again, a signal is sent to the cloud that the sink has been used along with the duration of the water flow. 20 . If the flush time exceeds the maximum flush time, there is a large leak or a faucet that is not turned off and this info is sent to the cloud to be forwarded to a facility manager 3.
Figure 17 illustrates an algorithm for monitoring for leakage: . If a water temperature 18 detected that 13 atypically high or low for a time that exceeds the detection time before leak calls, the info is sent to the cloud to be forwarded to a facility manager 3.
Figure 18 illustrates an algorithm for nudging at washbasin: . When a water flow to the toilet is detected, nudging for hand washing is initi- ated. Alternatively, when the weight load on the toilet stops. . Nudging can be a light indication 70, sound indication 71, or a mechanical movement 72 that reminds the toilet user to wash their hands.
DK 2023 70292 A1 44 . The nudging stops after acknowledgement from registered soap consumption and the water to the washbasin has been activated for longer than the time defined by the small flush washbasin water flow timer. » If it is detected during or after handwashing that the toilet has detected a big flush and the water flow timer is less than the big flush-handwash, the water flow timer starts nudging again. . If a predefined nudging timeout is exceeded, nudging prompts stop until the next toilet flush. . Daily nudging data is sent to the cloud e.g. after a nudging session is completed or at appropriate intervals.
For example, once a day if there has been a nudging activity in the past 24 hours. 18
